Globe Valves – Pressure Seal

Globe Valves - Pressure Seal

Kent Pressure Seal Valves are intended for high pressure and high temperature applications for all types of fluids, except where severe coking may occur. Because of their design and materials of construction, pressure seal valves are an excellent choice for nuclear steam generating stations, industrial/chemical plants, and thermal power plants. Pressure Seal Valves offer efficiency in flow passage and sealing, weight saving, ease of installation and simplicity in maintenance.
